woocommerce对接第三方支付(moonpay)信用卡接口总结

前言

又一个信用卡接口的对接需求，对接wordpress的woocommerce独立站

接口参数

接口参数一般由上游的api文档提供，每个通道之前有细微区别。

核心代码

主要功能逻辑都是一样的，组织订单参数->签名->提交->跳转返回结果中的支付链接->支付->处理支付结果->返回。

组织参数

//构造提交参数
  $Body = array(
      "merchantNum"         => $MerchantNo,
      "merchantUserid"      => $customer_name,
      "orderNo"             => $mref,
      "amount"              => $amountcents,
      "fiat"                => $currency_code,
      "payType"             => $payType,
      "notifyUrl"           => WC()->api_request_url( 'wc_huitrust_notify' ),   //异步,注意去掉  woocommerce_api_
      "returnUrl"           => $return_url,   //同步回调地址
      "returnfUrl"          => $return_url,   //同步回调地址
      "email"               => $customer_mail,
      "cellphone"           => $customer_phone,
      "attach"              => "",
  );

签名

      $checksum = md5('merchantNum='. $MerchantNo . '&orderNo=' . $mref . '&amount=' . $amountcents . '&keys=' . $private_key);
      $Body["sign"] = $checksum;

提交

//构建提交变量
  $args = array(
                        'timeout'     => 45,
                        'redirection' => 5,
                        'httpversion' => '1.0',
                        'blocking'    => true,
                        'body'        => $Body,
                );

  $postRequest = wp_remote_post($gateway_api, $args);

跳转

  if ($respj['code'] === 200) {
      $PayUrl = $respj['data']['payUrl'];
      } else {
           throw new Exception("Unable to create order code (" . $respj['msg'] . ")");
      }

      $query = "insert into {$wpdb->prefix}huitrust_data (ref, ordercode, email, orderid, total_cost, currency, order_state, timestamp) values ('". $mref . "', '0', '". $customer_mail . "','" . $order_id . "','" . $amountcents . "', '" . $currency_code . "', 'I', now())";
      $wpdb->query($query);

  wc_enqueue_js('
   setInterval(function(){
         $.blockUI({
         message: "' . esc_js(__('Thank you for your order. We are now redirecting you to huitrust.cc to make payment.', 'huitrust-for-woocommerce')) . '",
         baseZ: 99999,
         overlayCSS:
         {
         background: "#fff",
         opacity: 0.6
         },
         css: {
         padding:        "20px",
         zindex:         "9999999",
         textAlign:      "center",
         color:          "#555",
         border:         "3px solid #aaa",
         backgroundColor:"#fff",
         cursor:         "wait",
         lineHeight:     "24px",
         }
         });
    var start = new Date().getTime();
    while (new Date().getTime() < start + 3000);
    document.getElementById("submit_huitrust_payment_button").click();
   },1000);
       ');


  return
          '<div>'."\n".
          '<a class="button alt" id="submit_huitrust_payment_button" href="'.$PayUrl.'">'.__('Pay Now', 'huitrust-for-woocommerce').'</a>'."\n".
   '<a class="button cancel" href="'.$order->get_cancel_order_url().'">'.__('Cancel', 'huitrust-for-woocommerce').'</a>'."\n".
          '</div>'
   ;
 }

异步通知

 function check_huitrust_ipn_response()
 {
  global $woocommerce, $wpdb;

  if (($_SERVER['REQUEST_METHOD'] === 'POST') && preg_match("/wc_huitrust_notify/i", $_SERVER['REQUEST_URI'])) {
   $response = file_get_contents("php://input");
   error_log(__METHOD__ . PHP_EOL .print_r($response, true));

   if ( $response ) {
    $respj = json_decode($response, true, 512, JSON_BIGINT_AS_STRING);
    $private_key =   html_entity_decode($this->huitrust_merchantkey);
    $statustr = $this->huitrust_processing;

                  $checksum = md5('state='. $respj['state'] . '&merchantNum=' . $respj['merchantNum'] . '&orderNo=' . $respj['orderNo'] . '&amount' . $respj['fiatAmount'] . '&keys=' . $private_key);

    //error_log($checksum);
    //error_log($respj['sign']);

    if ($checksum == $respj['sign']) {
     $tm_ref = $respj['orderNo'];
     $check_query = $wpdb->get_results("SELECT orderid,order_state FROM {$wpdb->prefix}huitrust_data WHERE ref = '".addslashes($tm_ref)."'", ARRAY_A);
                      $check_query_count = count($check_query);

     //error_log("SELECT orderid,order_state FROM {$wpdb->prefix}huitrust_data WHERE ref = '".addslashes($tm_ref)."'");
     //error_log($check_query_count);

     if( $check_query_count >= 1 ) {
      if($check_query[0]['order_state'] == 'I' && $respj['state'] == '1') {
       $query = "update {$wpdb->prefix}huitrust_data set order_state='C', ordercode=" . $respj['platformOrderNo'] . " where ref='".addslashes($tm_ref)."'";
                         $wpdb->query($query);

       $inv_id = $check_query[0]['orderid'];
                         $order = new WC_Order($inv_id);
       $order->update_status($statustr, __('Order has been paid by ID: ' . $respj['platformOrderNo'], 'huitrust-for-woocommerce'));
       wc_reduce_stock_levels( $order->get_id() );
       add_post_meta( $inv_id, '_paid_date', current_time('mysql'), true );
       update_post_meta( $inv_id, '_transaction_id', wc_clean($tm_ref) );

       $order->payment_complete(wc_clean($tm_ref));
                         $woocommerce->cart->empty_cart();
      }
     }

    }
   }
   //接口返回
   exit('{"isSuccess":1}');
  }

 }

插件设置
